SETTING DEVICE FOR SULKY-PLOWS.

Application filed. March 2, 1911.

To all whom it may concern:

Be it known that I, RALPH E. GOULD, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Setting Device for Sulky- Plows, of which the following is a speclfication.

My invention relates to the class of wheeled plows, that is, one in which the plow or plows are supported upon wheels that move over the surface being plowed, and the object of my invention among others is to provide a device of this class by means of which a plow may be readily moved to position to plow a furrow and in whlch the depth of the furrow may be accurately de termined.

One form of device in the construction and use of which the objects herein above set out may be attained is illustrated in the accompanying drawings in which Figure 1 is a side view of so much of a sulky plow only as is needed to lllustrate my invention. Fig. 2 is a top view of the same.

In the accompanying drawings, the numeral 6 indicates the axle of a plow arranged to be supported as by means of wheels 7 shown in dotted outline. This axle is ofi'set as at 8 and on this oflset portion a plow-beam 9 is pivotally mounted as by means of a box 18 with a plow 10 supported at the lower rear end of the beam, the front end 11 being arranged for attachment of a whifile-tree or like means for the connection 7 of a draft animal, or other means for propelling the plow.

A hand lever 12 is secured as by means of a pin 5 at one end to the axle 6 and the frame is supported by this lever, it being understood that there is a lever at each side of the frame in the device herein illustrated and described which embodies two plows. This frame includes an arch 13, each lower end 1 1 of which is pivotally secured to a lever 12, and a brace 15 extends from each end of the arch forward, being attached at its forward end to a member 16 connected with the arch 13 and thus forming a rigid part of the frame and also a support for the 7 seat 17.

A curved rack 19 is mounted on the pin 20 that pivotally unites the hand lever 12 and the frame, herein above described, this rack being supported as by means of arms Specification of Letters Patent.

Patented Mar. 31), 1915. Serial No. 611,859.

' above described are of old and well known construction and the operation in which the handle 12 if unrestrained will move to the right or backwardly will be readily understood by those skilled in the art and further, it being remarked that the fulcrum of the lever 12 is in the axle 6, and the plow 10 with its'beam 9 is supported by the crank or off set portion 8 of the axle. The lever is secured to the axle 6 so that it is evident that if the axle is turned the lever will turn with it. The weight of the frame and parts supported thereon is transmitted to the lever 12 through the pin 20, so that the weight of the frame and parts supported thereby is opposed to the weight of the beam and plow. Therefore, the weight of the plow and beam 9 being greater than that of the frame and parts supported thereby, the handle 12 when released will be thrown rearwardly in a manner common to plows of this well known construction.

In the operation of plows of this class both hands of the driver are frequently occupied to properly guide the horses and for other purposes, and it thus becomes desirable to operate the mechanism for setting the plow by other than manual means, and the mechanism now about to be described provides means for accomplishing this result in an effectual manner, and the plow may be set to any depth required with certainty as to the operation of the parts to attain this end.

In carrying out my invention I provide a latch lever 28 that may be pivotally secured at one end to the rack 19 as by means of a pivot pin 29, passing through a slot 30 in said lever. The pin 29 is adapted to engage either one of a number of holes 31 in the rack 19 thus furnishing an adjustable pivotal point of attachment for the rack.

A foot lever 32 is rotatably supported as by the part 16 and the brace 15, this lever having a crank pedal 33 by means of which the lever is operated by the foot of the driver. The end of this lever has a crank arm 34 pivotally connected with the end of the latch lever, in the form shown this arm being adapted to pivotally engage any one of a number of holes 35 in the latch lever.

A detent trip pin 36 projects from the side of the bar 23 and underlies a detent trip 37 projecting from the side of the latch lever 28. As shown herein this detent trip is in the form of a curved rib overlying the pin, from which it will be seen that as the to immediately reengage'on'e of its notches and stop the'movement t the lever 12 at such time, and the provision of means for locating the pivot 29 in different; holes 31 enables" the disengagement of the detent trip pin from the detent trip, with the lever in different positions, and the plow may thus be located in different vertical positions to plow a furrow of greater or lesser depths, It will be found desirable in many instances to control the movement of the lever handle and as one means for attaining this end I mount a train of gears on said handle, this train including a pinion 2 7 and an intel-meshing gear 26 ,the' latter meshing with a gear 25s'ecuredto rotate with one of the wheels 7, said gear and wheel beingshown in dotted outline in Figs 1 and 2, A toothed rack is located on, the under edge of the latch lever 28, "these teeth being adapted to mesh with the teeth of the pinion 27"when the latch is moved downward disengage t detent. as cr i b ore les'cribed, it "being. understood that when this arrangement is employed the disengagement of thedetent should occur just before he meshing of the teeth of the pinion andraek,

h th i he e s0 n aged th ment ofthe lever will be controlled by the m v o P I Qil 7 which, ay b geared to rotate at'the proper speed,

f b de 's swsi t at he mechan s abovedescribed may be duplieated as desired, and especially in connection, witheach ihe levers qea d t oppos es destf the frame, nd: s c ll ha ii is apt e sential to the invention that the gears be employed to regulate the rate of movementof the l a 'i iese c rsmay di pen ed h h e re and h leve be r e q cve i de ih iw ish of he p as he ond i ns ex sting iii he mach ne.- Th per n f he dev e s as f llows :-The parts being in the, position s wn in Fig 1 h eiplow raised, Pr s u e iron hl Pedal W l cause he atch lever 28 to be swung downward on its pivot 29. In thismovementof the latch lever the detent trip 37 encounters the detent trip pin 36, moving the detent bar 23 and disengaging the detent 22 from the notches at the lower edge oi the curved rack 19. The construction of the parts and the distribution of the weight will atthis time tend to move the lever 12 to the right or backwardly, in an old and well known way common to plows of this constructiom-and should the gear and pinion 2;6-27 notbeemployed this bacle ward movement of the handle would con- 5 tinue untilthe pin 36 movesofi at the end of the trip when the detent 22 will at once engage the notchesin the under side of the rack 19 and thus stop the downward While.
